About the MCM 500 Deluxe Series Pens: is a traditional threaded cap pen design that features a ton of machined details. The fine thread pitch cap is easily removed and can be threaded on the non-writing end. The reverse (non writing) side has a subtile, but effective point for striking and compliance techniques. The main body is a machined spiral design. The pen writing tip, reverse tip and cap end all feature 8 sided faceting that matches the end of the cap as well.

New design features such as hidden fastener for cap tip and modified grooves for better ergonomics and cleaner overall look

Comes with O-rings that can be applied to the radial grooves on writing barrel for more grip

The reverse side has a subtile, but effective point for striking and compliance techniques

Compact (but still grippy) titanium clip

New cartridge pocket and spacer system allows for even more refill options than before

With spacer, compatible with Fisher Space Pen cartridges (included) as well as most Parker-style refills from Parker, Schmidt, Foray and more

Without the spacer, the 500 series will now take a Pilot G2 cartridge, one of the most popular and easy to get a hold of refills available

About Matthew Martin: Matthew Martin is the son of renowned knife-maker R.J. Martin and it is clear the apple has not fallen far from the tree. This guy has been turning metal into chips since he was knee high to a grasshopper! Each MCM piece is crafted entirely by Matt in his shop from top grade materials and attention to detail.Notes on Copper: This is a disclaimer for all you folks who slept through high school chemistry class or somehow not aware of the nature of copper. All metals will change colors and looks over time depending on use, environment etc. This is especially true with copper. This means it may get a darker, may change colors with patina, or it may get shiny and polished where it is rubbed by another material (like say your pocket). Take those pennies out of your pocket and see how different they all look. Well there ya go: thatís copper! If you want to keep your copper all shiny and new you will have to keep cleaning it with any of the homegrown solutions you can find with an internet search. OR, you can accept that what makes copper a cool material is that your piece will change over time and tell its own stories and truly become one of a kind.
